ABSTRACT:
A portable, self-contained, cummulative elapsed time recorder unit for personal use which records and stores data representing time spent by an individual working on each of a number of different work assignments, to provide a time record for billing purposes. The recorder unit includes a counter which is incremented when the unit operates in a timing mode to record a time element representing time spent working on an assignment, and a memory having a plurality of data storage locations, each assigned to a different work assignment for storing the time elements, the data storage locations being individually addressable by manually operable select switches. The recorder unit includes a display unit which provides a numerical display of the data stored at a selected memory location while the unit is operating in the display mode.
